The amount of comments still misunderstanding Usagihara to this day.. smh... Like I get why people dislike the tropes of overprotective friend, especially when they disregard boundaries for the guy (and especially if they're in love with the girl, etc.) but Momo is like the perfect example of how to do it right. Did people just conveniently forget the college student in the cafe chapter???
And she's literally not doing anything in this chapter, only making her observations and even admit to their budding relationship and NOT WANTING TO GET IN THEIR WAY. You guys make it sound like a crime for her to be insecure and feel negatively. She's still logical despite all of this and her challenge to Seno is to answer Takada's claim on their similarities, not for him to prove himself to her(he's already done that in their first shopping outing).
You guys need to learn from Takachad. He sees her kindness and good heart, and he barely even knows her.
I think some people here just lack reading comprehension in all honesty. Because I think it was pretty spelt out in this chapter.
